Firefox ☹️
I remember when Mozilla launched. Immediately downloaded the source and after much trouble, got it to build. This was the introduction to free software to a lot of people and Netscape releasing the source was a big deal at the time, there is a good documentary about it even.
For a long time Mozilla seemed like the champion of the open web and keeping the browser as a “user-agent” rather than a “corporate-agent”. But after relying on money from Google and mismanagement for so long, it really looks like they are done. The latest bit of news that they worked with Facebook to build “privacy preserving ad measures”, is the final nail for me and I'll be moving on.
